Dear Mr. Secretary:

The Advisory Board on Radiation and Worker Health (The Board) has
evaluated SEC Petition-00057-1 concerning workers at the Hanford
Nuclear Reservation under the statutory requirements established by
EEOICPA and incorporated into 42 CIR Sec. 83.13. The Board
respectfully recommends Special Exposure Cohort (SEC) status be
accorded to all employees of the Department of Energy (DOE), its
predecessor agencies, and DOE contractors and subcontractors. who
were monitored. or should have been monitored, for internal
radiological exposures while working at the Hanford Engineer Works
in: the 300 Area fuel fabrication and research facilities from October 1,
1943 through August 31. 1946: the 200 Area plutonium separation
facilities from November 1, 1944 through August 31, 1946; or the 100
B.D. and F reactor areas from September 1. 1944 through August 31.
1946; and who were employed for at least 250 aggregated work days
either solely under their employment or in combination with work
days within the parameters established for other SEC classes
(excluding aggregate work day requirements). The Board notes that
although NIOSH found that they were unable to completely
reconstruct radiation doses for these employees, NIOSH believes that
they are able to reconstruct components of the internal dose (other than
plutonium and fission products). and all external doses with the
possible exception of neutron dose which is still being evaluated.

This recommendation is based on the following factors:

¢ People working at the Hanford Nuclear Reservation during this time period worked in the
early years of nuclear weapons research and production.

e The NIOSH review of the available monitoring data as well as the available source term
and other information found that they lacked adequate information necessary to conduct
accurate individual internal dose reconstructions for plutonium and fission products
during the time period in question.

e NIOSH determined that health may have been endangered for these Hanford Nuclear

Reservation workers during the time period in question. The Board concurs with this
determination.

Enclosed is supporting documentation from the recent Advisory Board Meeting held in
Richland. Washington where this special exposure cohort class was discussed. If any of
these items are unavailable at this time. they will follow shortly.

Sincerely, ‘
